Inspired by the recent radiohead video, house of cards (and my lack of the equipment to do similar things), I decided to try and emulate something similar in Processing with a regular webcam image:

Sorry about the random pink in the video, it seems that vimeo added it in the conversion process. I take the intensity of the pixels from the image and use them as a Z-value for the horizontal lines that I draw. Simple, but I feel that it is pretty effective, especially when the lighting is right. More experiments with this are sure to come! 3D Webcam Lines Source Code
